摘要： The present invention provides for compositions and methods for preparing aqueous insoluble, ductile, flexible silk fibroin films. The silk films comprise silk fibroin and about 10% to about 50% (w/w) glycerol, and are prepared by entirely aqueous processes. The ductile silk film may be further treated by extracting the glycerol from and re-drying the silk film. Active agents may be embedded in or deposited on the glycerol modified silk film for a variety of medical applications. The films may be shaped into 3-dimentional structures, or placed on support surfaces as labels or coatings. The glycerol modified silk films of the present invention are useful in variety of applications such as tissue engineering, medical devices or implants, drug delivery, and edible pharmaceutical or food labels.

摘要： The present invention provides for methods of preparing silk nanoparticles and microparticles, methods of encapsulating an active agent into the silk nano- and microparticles and compositions comprising these silk particles. In particular, the silk spheres are prepared from phase separation of silk and polyvinyl alcohol (PVA), without exposure to an organic solvent. The method employs a chemical, PVA, which is an FDA-approved ingredient in drug formulations. Different parameters can be adjusted to control the size and shape of the silk spheres during the fabrication process. The silk particle compositions of the present invention may also encapsulate active agents or chemicals. Such compositions allow the active agents to be controllably and sustainably released to the target organs or tissues. The silk composition entrapping active agents also provides for a long-term storage medium for the active agents so entrapped. The silk nano- and microparticles of the present invention are thus suitable for a variety of biomedical and pharmaceutical applications, such as drug delivery or tissue engineering.
摘要翻译：本发明提供了制备丝纳米颗粒和微粒的方法，将活性剂包封在丝纳米和微粒中的方法和包含这些丝颗粒的组合物。特别地，丝球是通过丝和聚乙烯醇（PVA）的相分离制备的，而不暴露于有机溶剂。该方法采用化学品PVA，它是FDA批准的药物制剂成分。可以调整不同的参数，以在制造过程中控制丝球的尺寸和形状。本发明的丝粒组合物也可以包封活性剂或化学物质。这样的组合物允许活性剂可控地和可持续地释放到靶器官或组织。包埋活性剂的丝状组合物还为被捕获的活性剂提供长期储存介质。因此，本发明的丝素纳米颗粒和微粒子适用于各种生物医学和药物应用，例如药物递送或组织工程。

摘要： The present invention provides for compositions and methods of linking silk fibroin to active agents through the specific interaction between avidin and biotin, providing for functionalization of silk-based protein biomaterials. An avidin- or biotin-modified silk is a biomaterial platform for functionalization with a variety of correspondingly linked active agents, such as antibodies and growth factors. A variety of functionalized silk materials, such as silk hydrogel, silk micro/nanoparticles and silk films, can be prepared by the methods of the present invention. The functionalization strategies of the present invention are relatively easy, fast and feasible, and are thus useful in many biomedical applications.
